SY88782L
3.3V, 1.25Gbps High-Current, Low-Power
Laser Driver for Datacom Telecom
Applications
General Description
The SY88782L is a single supply 3.3V low power
consumption, small-form factor, driver for
telecom/datacom applications using FP/DFB lasers
at data rates up to 1.25Gbps. The driver can deliver
modulation current up to 90mA, and the high
compliance voltage it offers makes the part suitable
for high-current operation (with the laser AC- or DC-
coupled to it.) This device is intended to be used
with Micrel MIC3003 Optical Transceiver
Management IC which allows for modulation and
bias currents control and monitoring, automatic
power Control, and temperature compensation.
